Lehle 1@3 Switcher
The Lehle 1@3 Switcher is now discontinued and sold out. The 1@3 has been replaced by the new Lehle 1@3 SGoS Switcher. You can view the new SGoS Switcher here.
The Lehle 1@3 is designed to allow switching as a real True Bypass Switcher via gold-plated relays. You can switch between either three amps (A, B or C) or two amps and one loop. The input signal can only be routed to one output. When using the loop, the effects are connected to C and C->B. So you can switch smoothly between the direct (B) and the effect signal (C). The Lehle 1@3 can also be used to switch one guitar into a three amp configuration, but A,B and C cannot be used simultaneously.
Lehle 1@3 Features
1 - Input signal
The input signal enters this jack. It is automatically routed to A if the Lehle 1@3 is not active, and B and C are therefore muted.
2 - Loop (Return)
If this jack is assigned and C is activated, the signal applied here is routed to B. In this way, effect units can be serially routed into the amp, which is connected to B. Effects which influence your sound even when not active can thus be bypassed by pressing the B button. This means that they are in the signal path only when they are really needed.
3 - Output
The signal is routed with no semiconductors directly via gold-plated relays to Output A, B or C provided the corresponding button has been pressed. The input signal can only be routed to one output. The other two outputs are therefore muted. In case of a power unit failure the signal will be routed to A.
4 - Power supply
The Lehle 1@3 requires a power supply of between 8 and 20 V. Polarity is of no importance. The supply voltage is internally rectified and stabilized in order to guarantee trouble-free operation. A thermal cut-out automatically trips and switches the unit off if a short-circuit occurs. A correctly fitting plug connector for the power-supply jack of the Lehle 1@3 is supplied. This can be soldered to the required power unit if necessary.
5 - Master-Slave with other switchers
Each Lehle 1@3 can be easily retrofitted with a DIN socket in order to permit parallel operation with other Lehle switchers in master/slave mode.
6 - LEDs behind a magnifying lens
The high-intensity LEDs installed behind a magnifying lens make it easy to read the switching state (A, B or C) even under spotlights.
7 - Indestructible switching mechanism
The buttons which control State A, B or C are actuated inside the switch by means of a virtually indestructible switching mechanism.
8 - Solid box / easy to fix
The base of the Lehle 1@3 can be secured without difficulty. First remove the four housing screws for the cover, and then screw the base of the switch to a base-plate using the two screws supplied with the unit, the washers and the spacer elements.
